The History Behind Police Codes and Code 4

Police codes, including Code 4, were initially introduced in the late 1930s as part of the APCO (Association of Public-Safety Communications Officials) Ten-Signal system. Between 1937 and 1940, APCO standardized these codes to simplify radio communication for police departments nationwide. In 1974, these codes were further expanded and refined to meet the growing demands of modern policing.

Before police voice radios became widespread, APCO proposed Morse code-based brevity signals in the June 1935 issue of The APCO Bulletin. These early communication symbols were adapted from U.S. Navy procedure symbols and were designed to speed up message delivery in Morse code transmissions.

Over time, the transition to voice radios made the Ten-Code system—and terms like Code 4—a fundamental part of police procedure.
